Event Notification Report for October 23, 2012

AGREEMENT STATE REPORT - STOLEN TROXLER MOISTURE DENSITY GAUGE

The following report was received from the State of New York via fax:

"The Radiation Safety Officer for Materials Testing Lab, Inc. (NYS license no. C2274) called to report that a moisture density gauge (Troxler Model 4640, serial no.1003) was stolen around 9 a.m. today. The New York City Police Department was immediately called but as of 10:45 a.m. they have not responded. The gauge contains 40 mCi of Am-241/Be and 8 mCi of Cs-137. Materials Testing Lab staff are canvassing the area and posting reward flyers with a picture of the gauge. [The RSO] will keep NYS DOH informed of any significant changes to the situation. No press release has been issued at this time. New York City radioactive material program has been notified.

"NYS DOH Incident: #991

"Event Report ID No. NY-12-02"

THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL

Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf

This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source.

DEGRADED CONDITION DUE TO REACTOR HEAD VESSEL PENETRATION INDICATIONS

"On October 23, 2012, V. C. Summer Station Unit 1 (VCSNS) identified two reactor vessel head penetrations (19 and 52) that did not meet the requirements of 10CFR50.55a(g)(6)(ii)(D) and ASME Code Case N-729-1. The station is in a refueling outage (RF20) and the plant is currently shutdown and in Mode 6. The reactor vessel head (RVH) contains a total of 66 penetrations and inspection efforts are approximately 50% percent complete. There have been no previous repairs to the reactor vessel head penetrations and/or j-groove welds. The indications are not through wall as indicated by volumetric and bare metal visual inspections. The penetrations will be repaired to meet the requirements of 10CFR50.55a prior to returning the vessel head to service.

"The inspection results are reportable pursuant to 10CFR50.72(b)(3)(ii)(A). The NRC Resident Inspector has been notified."

The licensee will notify the State of South Carolina and local counties.

"On October 25, 2012, V. C. Summer Station Unit 1 (VCSNS) finalized our inspections of the reactor vessel head, which has identified a total of four reactor vessel head penetrations (19, 52, 31, and 37) that did not meet the requirements of 10CFR50.55a(g)(6)(ii)(D) and ASME Code Case N-729-1. The station is in a refueling outage (RF20) and the plant is currently shutdown and defueled. The indications are not through wall as indicated from volumetric and bare metal visual inspections. The penetrations will be repaired to meet the requirements of 10CFR50.55a prior to returning the vessel head to service.

"The inspection results are reportable pursuant to 10CFR50.72(b)(3)(ii)(A). The NRC Resident Inspector has been notified."
